Car enthusiasts started taking deliveries of the all new 2020 Chevrolet Corvette C8 a few weeks ago, that being said - time for upgrades!  Our pals over at SOUL Performance got their hands on one of the first cars off the line; as expected - their exhaust solutions are hand crafted to perfection and have further enhanced the driving experience to the next level!SOUL has developed a set of high flow sport cats, along with a free flowing rear exhaust system.  The sport cats utilize ..read more

The VGT turbo is nothing new to the Cummins ISX engine, since the introduction of the VGT style turbo on the CM870 ISX in 2003, each new rendition of the ISX has come with a VGT turbo. The latest ISX models, CM2250, CM2350, and X15 have the HE451VE turbo with electronic actuator from the factory.  These turbos are great when functioning correctly, but like anything else - they fail over time.  VGT turbos can be replaced as a whole assembly, turbo + actuator, or can be replaced ind ..read more

A/R stands for Area over Radius.  Area is the size of the housing inlet and radius is the the diameter of the housing.  Before every keyboard warrior jumps down my throat...this is just a basic explanation for the sake of a general overview -we don't need to get lost in the weeds, we'll leave that for scientist and engineers :)The larger the AR number, the larger the housing is.  Larger housings support higher horsepower levels, but take more exhaust gasses to turn the wheel and m ..read more

Yes, big claims from an even bigger (FAT) man - now that I have your attention; please allow me to plead me case.There are certainly BIGGER, BETTER, & More EFFICIENT turbos on the market, but I think this turbo does all those things pretty well, while any other "Better" turbo will likely only exceed at one of those attributes. The BorgWarner S410SX - 78MM /1.32 AR is easily the best C15 turbo on earth, and here's why: 1) Its a bolt on upgrade for any single turbo cat.*&nb ..read more

The factory HT60 on the Cummins N14 and 855 engines has a unique flange pattern and abnormal mounting orientation that makes it very difficult to retrofit a more modern upgraded turbocharger.With this in mind, we set out to create an upgrade that was a direct replacement from an installation stand point. Depending on the original spec and horsepower out put, your N15/855 could have had a multitude of different chargers from the factory, we have listed them below. As you can see above, our N14 up ..read more

We often get asked about turbo blankets and ceramic coating on our manifolds and turbine housings, so I thought I would take a second to explain what these heat coatings and blankets actually do.First we need to start with the basics properties of gasses and thermal properties. It's common knowledge that things can expand and contract when temperatures change; What's going on in your new turbocharger is no different! On the exhaust side, as the exhaust gas temperature rises, the gasses expand ..read more

VOLVO / MACK Holset VGT Turbo InterchangeabilityWe have touched on this topic before, but some things are worth a second look. While Holset has 1000s of part numbers for their VGT turbocharger, I know those 1000s of numbers superseded to only 100s of turbos, and I THINK those 100s of turbos can be consolidated down to 10s of turbos. Taking a step back - Holset has “families” or “series” of turbos. For example, HE300 series turbo, which then further breaks down to an HE341VE, HE351VE, etc - the ..read more

It seems like I have been hearing about this “Monster” factory Detroit turbo for years. Well, I finally figured out what it was and then proceeded to get my hands on one! From what I understand, they come factory on the Detroit Series 60 HK Engines, which is an industrial version of the common road going Series 60 that we all know and love. This engine looks like it could originally be spec’d with up to 665HP with a 2300RPM rev limit!With horsepower like that, it makes sense that the stock tur ..read more
